The Array contains some non-empty arrays . i need to fetch respective non-empty array and print the data . eg: array 2 has variable as importTroubles->troubleMessage how can i print that?
Array
(
[0] => stdClass Object
(
)
[1] => stdClass Object
(

[2] => stdClass Object
(
[return] => stdClass Object
(
[failureMessage] =>
[importTroubles] => stdClass Object
(
[kind] => ParseError

foreach ($object as $items) {
if($items !== '')
{
foreach ($items as $item) {
echo "ERROR".$item->troubleMessage;
}
}
}

Thanks for your efforts

Answer 1

Make use of php function empty()
Change your if condition as in below code :
foreach($result as $object) {
foreach ($object as $items) {
if( !empty($items) )
{
foreach ($items as $item) {
if( isset($item->troubleMessage) )
{
echo "ERROR".$item->troubleMessage;
}
}
}
}
}
Now it will echo only if $items has values.

Answer 2

You don't have to iterate each object if you're only looking for a single specific item nested within it. You can just refer to that item directly.
foreach ($your_array as $object) {
if (isset($object->return->importTroubles->troubleMessage)) {
echo $object->return->importTroubles->troubleMessage;
}
}
If you check if that specific nested object variable is set, it will ignore any empty objects.

Answer 3

change your if($items !== '') to if(!empty($items)) or if($items) or if($items[0]) hope it helps

Answer 4

You could use Collection
use Illuminate\Support\Collection;
$collection = new Collection($result);
$items = $collection->filter(function($object) {
return isset($object->return->importTroubles->troubleMessage);
})->map(function($object) {
return $object->return->importTroubles->troubleMessage;
});
